Abstract: A fluid control valve that includes an electromagnetic actuator in the form of a pot-shaped magnet (7) as well as an armature plate (6) controllable by the actuator, said armature plate including a closing member (5) cooperating with a valve seat (17, 18). The armature plate (6) is compensated in pressure through a connecting passage (19) within the closing member (5) whereby the pressurized coil chamber (20) of the actuator is pressure sealed to the outside with its cover 13 which is made in one piece with the magnet housing (8) to be able to employ the valve also in the high-pressure range.

Abstract: A hydraulic assembly including a reservoir, a pump arrangement, hydraulic control elements, and an electric motor for the pump arrangement whose components are coaxially arranged along a straight axis, possibly overlapping one another partially, is constructed having smaller dimensions and with simpler construction. The pump arrangement is therefore an axial piston pump (2, 2a, 5, 6) whose cylinder block (2) is oriented coaxially to the other components and the cylinder block (2) is provided with several pump elements (6).

Abstract: A fluid valve having a switching magnet (2) detachably mounted on a valve housing (1) whereby an essentially annular retaining disk (7) is fastened to the valve housing (1), which is provided with a first fastening device (12) and which engages with a second fastening device (14) the supporting housing (3) surrounding the coil (4) of the switching magnet (2) at the opposite side of the valve housing (1) preferably in the way of a snap-on connection. The fastening of the switching magnet (2) to the valve housing (1) may thereby be performed in a simple and cost-effective manner.

Abstract: A pressure medium cylinder with a piston rod (1) extending out on one side has a cylinder floor (3), which closes off the cylinder tube (2) on the piston side with a fastening element (4), and a function block (5), placed upon the former, with function elements (6 to 9). In order to improve the connection between cylinder floor (3) and function block (5), the cylinder floor (3) has at least one cylindrical outer connection area (17) into which the pressure medium lines (19, 20) that lead to the work chambers (11, 18) open to the outside and onto which the function block (5) is placed and attached with a sealed through-hole (21), into which the pressure medium lines of the function elements (5 to 9) open.

Abstract: A spatially-adjustable patient positioning surface (1) of an operating table, for example, is connected to at least two hydraulic cylinders (2, 3, 3′, 24) which are separately controllable by two control elements. The control elements are combined in at least one rotary distributor (26, 27) that is adjustable by means of one common adjustment arrangement (25).

Abstract: A valve arrangement using at least two piston slide valves flanged in series with their valve housings. The number of required line holes are reduced as are the number of sealing sites.

Abstract: A refrigeration system for freight vehicles having inwardly open profiling for air ducting in the floor, the side walls and the doors, the profiling in the region of the vertical walls and doors being formed of vertically extending grooves or channels. In order to ensure uniform supply of cooling air to the grooves or channels of the vertically extending profiling and to ensure uniform discharge of the cooling air in the region of the lower ends of the grooves or channels independently of the loading condition, each of the side walls has at least one lower, preferably one lower and one upper, substantially horizontally extending air ducting channel, the lower air ducting channel being arranged at a spacing from the floor, and the vertical profiling discharges into the air ducting channels.
